Hi all,

Ever since commit cafa0010cd51fb71 ("Raise the minimum required gcc
version to 4.6"), I felt bored when looking at my test build logs, as I
was no longer discovering many real issues.  Hence I started wondering
if the modern gcc versions are really catching these classes of bugs
caught before with gcc 4.1, or if they just go undetected.

I reverted some changes and applied some fixes, which allowed me to
compile most of the kernel with gcc 4.1 again.  I built an
m68k/allmodconfig kernel, looked at all new warnings, and fixed the ones
that are not false positives.  The result is a patch series of 5
patches, of which one or two fix real bugs.

Thanks for your comments, and for applying where appropriate!
